How to Conduct the Heat Away inside LED Chips?
The heat generated from the LED chips is passed along the aluminum heat sink via soldering and other interface materials. If one of the parts is poorly designed such as discontinuity in poor manufacturing process, the heat will be accumulated inside the LED package and cause overheating, which eventually burn the chips.
On the other hand, for the heat sink part, it should provide large surface area to dissipate the heat to surroundings. These flood lamps caught fire because their lighting engineers underestimate the heat generated of the product and use the poorly designed heat sink in the products. We should take extra precaution if we are going to buy the stadium lights having this design.
